Rails                  
                                          
                                          
  
                                          
  
                                          
                                          
 Trains  Are  So  Constructed  That  They 
 Have To Follow A Set  Path. This Path Is 
 Called  A "Railway",  Which Is Comprised 
 Of Two Metal Rails, Hence  Its Nickname. 
                                          
 Because The  Low  Friction  Between  The 
 Wheels Of  The Train And The Rail Metal, 
 There Are  Limits For  How Acute A Curve 
 Can  Be,  And Even More So  For How Much 
 The   Ground  Under  The  Rails  Can  Be 
 Sloped. Thus A Railway Is Often Not  Led 
 On Top Of Hills, Rather  Through Them In 
 TunnelS   (If   They  Are   Large),   Or 
            Artificial ChasmS.            
                                          
 There  Will Be  Trees On The Side Of The 
 Rails, But Not Too Close,  Or They  Will 
 Be  Cut  Down By  The  Railway Janitors. 
 There  Will  Be  Plains, And  Bodies  Of 
                  Water.                  
                                          
 Trains Go  By  Day  And By  Night. Along 
      The Way, There Is Information       
 Scattered,  Often Put On  Top  Of Poles, 
 To Be  Interpreted By The Train Drivers. 
 Different  Parts  Of  The  Railway  Have 
          Different Speed Limits.         
                                          
 Sometimes, Trains Have To Stop And  Wait 
 For Something To Happen, Far Away.  This 
 Is  Signaled  By  Red  Or  Green Lights. 
                                          
                                  
                                          
 Many People  Follow The  Rails  By Foot. 
 Often  This Proves  To  Be  The  Shorter 
 Path  Between  Two Points. However  This 
 Is  Frowned  Upon,   And  Very  Impolite 
         Toward The Train Drivers!
